Estoy tratando de convertir el resultado JSON-RPC de la propiedad de bits comprimidos de un bloque en un flotador de C# con la siguiente restricción
//3 bytes mantissa, the leading byte as exponent (where only the 5 lowest bits are used) and its base is 256
¿Hay algún dato de muestra que pueda usar para verificar que mi implementación está funcionando?
Una cadena JSON-RPC y su correspondiente salida de 256 bits en formato Big Endian serían de gran ayuda.
